Title: Two-stage hydraulic master cylinder
IPC: B60T11/224
Filed: 1945-11-29
Abstract: 613,527. Hydraulic master cylinders. WAGNER ELECTRIC CORPORATION. Nov. 29, 1945, No. 32282. Convention date, Jan. 4. [Class 103 (i)] In a two-stage master cylinder such as described in Specification 575,417, in which the cylinder initially slides bodily to cut off communication thereof with the reservoir and the low-pressure piston is rendered ineffective at a predetermined pressure by flow through a valve-controlled passage in the high-pressure piston, this passage is restricted to provide gradual transition from the low to the high pressure stage and a passage through the low-pressure piston which byepasses the restricted passage when the pistons are retracted is closed by initial forward movement of the highpressure piston relatively to the low-pressure piston. The cylinder 14 is slidably supported within the reservoir 1 by the outlet 15 of the cylinder and the rear end thereof which respectively slide within and over members 3, 12 screwed into the reservoir. A spring 11 bearing through a washer on the inner end of the plug 3 normally holds the cylinder in the position shown in which it communicates with the reservoir through passages 16. The highpressure piston 18, 23, 30 slides in the cylinder member 12 and in the low-pressure piston 36 which normally abuts on a fixed ring 35. A passage 41 through the head 30 of the lowpressure piston 'is normally' closed by a valve 31 acted on by a spring 26 and connected to a normally unseated valve 27 to which is attached a sealing cup 28. The space at the rear of the piston 36 is normally connected to the forward cylinder chamber 14<SP>1</SP> by passages 43 in the piston. The piston 23, 30 when initially moved by the pedal carries the cylinder forward by friction to close the passages 16 and then engages the piston 36, a valve member 38 sealing off the forward chamber 14<SP>1</SP> from the space at the rear of the piston 36-which, however, receives' liquid from the reservoir through passages 14a, 17 past the sealing-cup 28 and passages 44. When the pressure in chamber 14<SP>1</SP> acting on the valve 31 against the pressure of the spring 26 is sufficient to unseat the valve, the chambers at front and rear of the piston 36 are connected together by the passage 41 and the piston thus rendered ineffective. The passage 41 is restricted to delay equalization of the pressure at the two sides of the piston 36 so that the transition from the low to the high pressure phase is rendered gradual and the change-over tends to be further delayed if the pedal is moved rapidly.

Title: Mechanism for the axial adjustment of components of an optical system
IPC: G03B17/14
Filed: 1966-07-20
Abstract: 1,144,702. Variable focal length lens mounts. BELL & HOWELL CO. July 20, 1966 [Aug. 13, 1965], No.32584/66. Heading G2J. An optical system having axially adjustable components, as in a zoom lens, comprises lens cells 17, 45, 46, 47, as shown. Fig. 3 is a reverse aspect view of Fig. 1. A mechanical linkage between zoom lens 45 and lens 46 is provided, so that as lens 45 moves, lens 46 makes a compensating movement to maintain the focus. Cell 17 is a front focusing component comprising lenses 22, 23, 24, and is mounted in sleeve 18 which is screw-threaded for axial movement. The other three cells are mounted on three support rods (40, 41, &c.), extending parallel to the optical axis. Cell 47, comprising lenses 49, 50, is rigidly secured, by a holder 51, to the support rods, and acts as a rear focusing unit to focus the light passing through the system on to the image plane (not shown). Cell 45 is the zoom member, and comprises lenses 62, 63, 64, which are mounted in a frame 61. This has an integral radially extending lug portion 68 which has a bore through which rod 40 passes. Thus frame 61, and hence cell 45, can slide along rod 40. Cell 46 comprises a single compensating lens mounted in a frame 71 which, similarly to frame 61, is arranged to slide along the support rods. The zoom component 45 can be moved from one end of its traverse to the other, as indicated by arrow 88, by means of a handle 76, 77, which turns a pinion 82 engaging in a rack 83 rigidly attached to frame 61. A bell crank lever 89 having a pair of angularly disposed legs 90, 91, (leg 90 having an arcuate slot 96) is pivotally connected by a screw 93 to the fixed holder 51 of cell 47. A boss 98 which is integral with the frame 61 of cell 45 can slide in slot 96, so that as cell 45 makes a traversing movement, lever 89 pivots accordingly. Leg 90 of lever 89 has a recessed end 99 which engages a pin 100 mounted in a boss 101 which is integral with frame 71 of lens cell 46. Thus as lever 89 pivots on screw 93, frame 71, and hence cell 46, is caused to slide along the support rods. Accordingly, as zoom cell 45 moves, a corresponding movement is imparted to cell 46, so that fixed cell 47 will focus on the image plane. The operable relationship between cells 45 and 46 is such that, while cell 45 traverses from end to end of its range (arrow 88), cell 46 is required to move backwardly and then forwardly, as indicated by arrow 87. This is provided for by the design of the lever 89 and cam slot 96. A spring 102, pivoted on screw 93, has one end 103 engaging against pin 100 of cell 46, and the other end 104 engaging against pin 109 of fixed cell 47. Thus the spring prevents play or looseness in the control mechanism by holding pin 100 firmly in recess 99, and holding boss 98 firmly against the edge of slot 96.

Nov. 25, 1935, No. 32679. [Classes 38 (iii) and 38 (v)] Protective equipment for a compound wound motor M com prises a reversecurrent relay R having a coil W1 carrying the motor current, and adapted when a reverse cur rent ofpredeterminec value flows in the motor circuit by reason of the motor regenerating, to disconnect the motor from the supply, means W2 also being provided for holding the relay R in its operated position until the speed of the motor falls to a safe value for re-making the motor circuit. The motor M may drive a generator G supplying auxiliaries on an electric locomotive, and may have a shunt field or a field F2 supplied from the generator. When the line voltage falls temporarily and the relay R is operated by the reverse current flowing in the motor circuit, contacts C are opened to open a line circuit breaker CB, and the relay R is latched in its operated position until the latch is released by a coil W2 connected across the generator G in series with a polarizing coil on the relay armature W3, this release taking place when the generator voltage, and, therefore, the motor speed has dropped to a predetermined small value. The reclosing of the relay R may be effected in accordance with the motor armature voltage or the voltage across a shunt winding of the motor. Alternatively, a timing element may be provided for delaying its reclosure.
